A roller massaging mechanism of a type having a pair of right and left massaging rollers mounted on an intermediate portion of a rotary shaft in a slanted fashion relative to an axis of the rotary shaft, and includes a switching member for selectively switching the position of the pair of right and left massaging rollers into one of a kneading position where the pair of massaging rollers are slanted opposite to each other and a non-kneading position where the massaging rollers are slanted parallel with each other. When the massaging rollers are caused to assume the kneading position by the switching member, a kneading massage operation is performed, while when the massaging rollers are caused to assume the non-kneading position, a massage operation other than the kneading massage operation such as a finger pressure-like massage or a tapping massage is performed
